T-SQL (SS2K8) :: Get Script To Output Only 2 Decimal Places For Amount Column From Select Statement?

I have a routine that generates an HTML email and sends it just fine, but one of the columns ends up with 4 decimal places for a column datatype of money. How can I get the script to output only 2 decimal places for the amount column from the select statement?

Here's the script:
declare @tableHTML nvarchar(max) ;
set @tableHTML =
N'<h1>Revenue Report</h1>' +
N'<table border="1">' +
N'<tr><th>Amount</th><th>Index</th><th>CompObj</th><th>Rev Type</th><th>Program</th>'+
CAST ((SELECT td=SUM(dbo.tblAllocations.Amount),'',
